Approach
Start small.
Build what lasts.
A clear path from a useful first win to a system your business can rely on.
01 — Find
Map the friction
We understand the real workflow, the handoffs and the cost of leaving it as-is.
02 — Focus
Choose the win
We isolate one high-value opportunity and define what success will look like.
03 — Build
Make it useful
We design, integrate and test a focused system around the way your team already works.
04 — Grow
Earn the next step
Once the value is visible, we extend the system with confidence—not guesswork.
Open source
Built in the open.

OfflineSmsAI
A .NET MAUI Android app that runs a GGUF language model fully on the phone through llama.cpp. No network, no API key, no cloud.
Text the phone a message containing a flag such as #ai and it replies over SMS from its own local model. It includes a streaming chat screen, resumable model downloads with GGUF verification, per-sender rate limits and loop protection, so two phones never end up answering each other.
